This invention has been devised with the object of providing improvements in boot and shoe heels of the class in which detachable wearing surfaces are employed. The inven 5 tion consists more particularly in the means employed in attaching such surfaces to the heel and which means are designed to provide for the attachment and detachment being effected without the employment of skilled labour.v This will enable. anyone to replace a worn surface with a new one, in a few moments.

r The invention comprises the combination with the heel, and with the thickness of leather or other material forming the wearing surface, of a square'or otherwise cornered socket member let into the heel bottom, a female member allixed to the inside face of the wearing surface and shaped to form a neat fit within the socket, and a locking screw pin extending through both socket and female member and adapted to lock the one within the other by an action by which the wearing surface is drawn up closely. against the heel bottom. These may, however, be so designed as to allow for a cushion heel being provided for, by the insertion between the heel and the wearing surface, of'a strip of resilient material.

The said locking screw pin may be held as a permanent fitting within the heel so that it projects down within the socket and is free to turn while being held from longitudinal movement, and the female member made with a female screw threaded hole to receive such pin, or alternatively, the screw pin may be made as an attachment'to the female mam--v ber and to screw up lnto a female screw threaded hole in the top of the socket. In 0 either instance, also, the locking portion of the pin and its female threaded receiving hole may be made with mutilated'threads. as in gun breech block construction, to allow of the one sliding into or on to the other and then being locked by a partialrotation of the pin.

The invention is illustrated in the accompanving drawings, in which r Figure 1 is a sectional side elevation of a heel showing the wearing piece secured thereto by means in which the locking'pin is fitted to remain in the heel. 7, Y

J -Aisthe heel which ismade of any of the usual materials and forms. B is the wear ng strip'of leather to be secured to thefsurface of the heelso that it may be removed at will and'be replaced by a new one wh'enever desired. i v 3 In the form of the invention shown in the drawin'gs,*a metallic plate C is affixed to the bottom'of the heel A, to cover whole or part of'its surface as may be desired, if covering a part only, being .let into such surface so as to be flush therewith, as in the drawings. This plate C ismade in one with a socket D The top of the socket-is made witha hole F passing through it which hole is plain in the form s'hown'inFigur'es 1 to 4.

A metallic plate G isalso combined with the wearingfstrip B so that it covers its top side. T l1is plate has formed the ewith, a a.

male member H, which is of such ashapean'd size as to be capable of fitting with a close fit into the'socket Dt when the wearing strip is faces makinga close joint. p

The said socket and female member are .made of any approvedshape in sectional plan as. to provide that'whe'n fitted together, the. female member is incapable of, turning in the socket." This may be. obtained by shaping "them of the square form shown in the draw- 'ings, or of other approved angular form.

pin being rotated. To provide for such ro-' tation being effected, the bottomend of the pin is made with a screw driver slot. This arrangement providesthat to secure the wearing strip to the heel it is placed on the heel so that the female member enters the socket and the pin end enters the threaded aperture J in the female member; Then byturning'the pin in the proper direction, the pin will screw into the female member and draw it right in so that the two surfaces will be brought into close locking engagement. The strip may be removed at any time by a reversal of these operations.

This form of fastening will allow for a resilient pad N, of rubber or like material, being placed between the surfaces of the heel A and the metal plate G carrying the wearing surface B, to extend over the full area of their contact. This will give a cushion effect The necessary freedom for the Wearing surface to move upward is provided for by allowing free spaceslbetween the top of the recessE and the head M of the screw pin, and between the top of the socket D and the female member H. f a r The plate G to which the wearing surface B is secured may, if desired, be made with a thickened portion G on a suitable part of its edge, the surface B then being fitted within such portion as shown in order that a uniform bottom face is obtained. This portion G will then serve as aprotector against the tendency, so very common, to wear down on one edge of theheel. I

'The'hole left in the wearing surface for the screw pin K may be filled with wax or other access to the pin. a
